Where is L26500 Emergency .plt firmware

HP Recommended
HP DesignJet L26500
Microsoft Windows 10 (64-bit)

Hello. I have 2 HP DesignJet L26500 that are giving me generic error 79:04. Got new hard drives for them and still receiving error. I read in the manual i could force a firmware update with an emergency .plt but the link provided in the manual does not direct me to downloadble .plt. I can only download latest firmware .fmw file.  Where can I download .plt for L26500 DesignJet? Im running out of ideas for fixing the machines. Thank you in advance.
